Patented July 13, 1948 WEB ROLL SUPPORT Charles H. Petskeyes, Davenport,Iowa, assignor to Gellman Manufacturing Company, Rock Island, 111., acorporation of Illinois Application June 9,1945, Serial No. 598,470

1 Claim. (01. 24268) This invention relates to certain novelimprovements in web roll supports and more particularly the invention isconcerned with and relates to an arrangement for preventing theoverriding or backlashing of a roll of paper during the wrappingoperation of the machine.

In this aspect of the invention, the primary object is to provide anarrangement capable of these accomplishments, which will be economicalin manufacture, highly eiiicient in use, and simple in construction, anarrangement which can be manipulated with safety and ease when mountinga roll of paper in position with respect to the wrapping mechanism.

Another object of the invention of equal importance is the provision ofa core for each end of the roll of paper in which core is incorporatedfrictional means for preventing overriding or backlashing of the roll ofpaper and which core, while being capable of these accomplishments maynevertheless be inserted in the end of the roll of paper in theconventional manner. This latter feature permits the use of standardizedrolls of paper.

The present invention is intended to be used in connection with a breadwrapping machine such as that disclosed in United States Patent Nos.2,276,590; 2,252,028; 2,235,503; 2,232,558 and 2,230,797.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings showing the preferred form of construction, and in which:

Fig. 1 is a fragmentary perspective view of a bread wrapping machineshowing my improvements incorporated therein;

Fig. 2 is a vertical sectional detail view of the paper roll mountingcore block embodied in the invention.

The drawings illustrate the preferred form of construction by which theseveral objects of my invention are accomplished.

The conventional bread wrapping machine, as is evident from the severalpatents hereinbefore referred to, comprises side frame members I and lhousing the bread conveying and wrapping mechanism, the latter not beingshown in the drawings of this application, as such mechanism does notconstitute any part of the present invention.

Associated with these frames l0 and H are one or more screw shafts l2,each having a suitable hand wheel |3 to facilitate rotation of theseshafts. Extending parallel'with these shafts l2, between the frames I0and II, are' stabilizer bars [4.

Spaced bracket elements are indicated at l5, and these bracket elementsare provided with enlarged bearings |6 at their inner end portionsthrough which the screw shafts l2 work. These bracket elements alsoprovide depending feet I! bifurcated as at I8 to provide a seatengageable with the stabilizer bars I4. The bracket elements l5 extendoutwardly from the side frames Ill and H, as at l9, and the extremitiesof these portions l9 provide bearings 20.

Associated with each of these bearings 20 is a stud shaft 2! having areduced portion 22 bearing threads 23 for threaded engagement with a nut24. The reduced portion 22 of the stud shaft 2| projects through amounting disc 25 having fixed connection with the bearing 20 by means ofa pin 26. Secured to the outer face 21' of this mounting disc 25 is afriction ring 28 formed of fiber or other suitable friction material.

The stud shaft 2| has an enlarged portion 29 which bears against themounting disc 25. This enlarged portion 29 projects through an opening30 formed in a core or plug 3| in which opening there may be positioneda suitable bushing. The enlarged portion 29 of the stud 2| has a headportion 32 which fits into a socket 33 formed in the plug 3 The plug 3|is freely rotatable upon the enlarged portion 29 of the stud shaft 2|and provides an internal flange 34 riding within an opening 35 formed inthe friction ring 28.

The medial circumferential surface 31 of the plug 3| provides a taperedshoulder 38 which is adapted to engage the rim of the bore 39 throughthe roll of paper 39.

The plug 3| in its outer portion provides a recess or socket portion 40into which fits the mounting disc 25 and. the friction ring 28 in amanner such that opposing faces of the ring 28 and the plug 3|, asindicated at 42, will have frictional engagement with respect to eachother.

In bread wrapping machines of the type illustrated in the aforementionedpatents, the paper roll 39 is intermittently rotated by a mechanismwhich exposes successively, sections of the web 43 of the roll 39 in thearea of the wrapping operation. Mechanism of this type has a tendency tocause the roll to rotate suddenly and end with a slight jerk. In soacting, the paper roll 30 often overrides the intended degree ofrotation of the paper roll and, as a result, considerable While I haveillustrated and described the pre--' ferred form of construction forcarrying my invention into effect, this is capable of variation andmodification Without departing 'fromflthe spirit of the invention. I,therefore, do not Wish to be limited to the precise details ofconstrue-- tion set forth, but desire to avail myself of such variationsand modifications as come Within'the" scope of the appended claim.

Having thus described my invention, what I Claim as new and desire toprotect by Letters Patent is:

A mounting core for a roll of paper comprising a non-rotating studshaft, a mounting disc, means carrying said stud shaft and havingconnection with said mounting disc to prevent rotation of said mountingdisc relative to said shaft, a paper roll supporting core mounted onsaid stud shaft and having a socket portion, a friction disc mounted insaid socket and supportedby said core and adapted to have facialengagement with said mounting disc, substantially as described.
